Image processing
(1) Charging: Applies negative charge on the
surface of the photoconductive drum.
(2) Original exposure: Converts images on the
original into optical signals.
(3) Data reading: The optical signals are
converted into electrical signals.
(4) Data writing: The electrical signals are
converted into light signal (laser emission)
which exposes the surface of the
photoconductive drum.
(5) Development: Negatively-charged toner
adheres to the photoconductive drum and
forms visible image.
(6) Transfer assist bias: Improves transfer
efficiency.

(7) Transfer: Transfers the visible toner image
on the photoconductive drum onto paper.
(8) Separation: Separates paper with the toner
image from the photoconductive drum.
(9) Fusing: Fuses the toner image onto the
paper by applying heat and pressure.
(10) Cleaning: Scrapes off the residual toner
from the drum.
(11) Discharging: Eliminates the residual
negative charge from the surface of the
photoconductive drum.
